Get started with FlashAir

What can FlashAir do?

FlashAir is an iSDIO standard compliant device with wireless LAN functionality and a built-in micro computer.

Devices with an SD card slot such as cameras and PCs (i.e. SD host devices) will recognize the FlashAir as a
SDHC memory
card and be able to read/write data. Furthermore, SD host devices that support iSDIO commands can control the
FlashAir's
wireless LAN directly.

Since the FlashAir has a built-in web server, Wi-Fi devices can connect to the FlashAir and access its
contents using
HTTP (HyperText Transfer Protocol) on any modern browser.

Wireless LAN

Control Wireless LAN functions, such as enabling AP/STA mode, using both simultaneously
(bridge mode), and scanning
SSIDs.

HTTP

HTTP communication via Wireless LAN

Web server

By issuing HTTP GET requests to files on the FlashAir, you can download them. The FlashAir
API includes CGI commands
to get list of files and to customize your configuration.

FlashAir Versions

There are four versions of FlashAir cards:
First Generation (W-01) ,
Second Generation (W-02) ,
Third Generation (W-03) , and
Fourth Generation (W-04) . In the second generation, the SD memory card corresponds to Class
10, the fourth
generation corresponds to UHS speed class 3, and the speed is increased, and the transfer rate by the fourth
generation
radio is about 2.9 times the third generation.

The first generation firmware version 1.00 series, second generation the 2.00 series, third generation the
3.00 series,
fourth generation follows the trend and is called the 4.00-series. In 2.00 series, the API specification has
been
greatly expanded. Application developers should pay attention to differences in behavior due to firmware.

Read / write maximum speed

Read: 90MB/s
Write: 70MB/s

—

∗We calculate 1 MB/sec as 1,000,000 bytes/second. The maximum transfer speed is the
best value obtained under
specific conditions in the Toshiba Memory test environment, and it does not guarantee the speed in the
equipment
used. Read / write speed may vary depending on the condition of the equipment, etc. to be used. The transfer
rate
of a conventional SD interface will be reduced compared to the UHS-I interface.

Wireless transfer rate

About 31.4 Mbps

About 10.8 Mbps

∗Measured values are measured independently by the manufacturer, and do not guarantee
the actual transmission
speed. The actual wireless transmission speed varies depending on the equipment and environment used.

UHS

It is an interface that can be used with SDHC / SDXC memory card, and high speed performance
can be obtained by using
with compatible equipment.

UHS-I
UHS Speed Class3

—

Speed class

It is a standard that specifies the data transfer rate with the SD host device. In Class 10,
the data transfer speed
at read / write is at least 10 MB/sec.
